Calvin Klein's ex Nicholas Gruber pleads guilty to assault

Fashion mogul Calvin Klein's ex boy-toy Nicholas Gruber pleaded guilty on Thursday to misdemeanor drug charges and showed up in court with a scantily clad blonde woman, according to reports.

Gruber, 22, was arrested in April after allegedly punching a 20-year-old man he'd brought home after a night of partying. A strip-search revealed cocaine hidden in Gruber's underwear.

The male model made out with conditional discharge, dependent on performing 20 days of community service in either New York or Californa, and staying out of trouble until December.
